  $headers .= "\r\nContent-Transfer-Encoding: 7bit\r\nX-Mailer: Microsoft Office Outlook 12.0"; 

 	//Create the Transport
	$transport = Swift_SmtpTransport::newInstance('mail.example.com.my',25)
      ->setUsername('php.mailer@example.com.my')
      ->setPassword('abc123456');
	
	//Create the Mailer using your created Transport
	$mailer = Swift_Mailer::newInstance($transport);
	
		//Create a message
	$message = Swift_Message::newInstance('Meeting Invite Testing')
	 
	 ->setFrom(array('php.mailer@example.com.my'))
	 ->setTo(array('example@example.com.my')) 
	 //->setTo($to_mail) 
	 //->setCc($cc_mail)
	 //->setBcc($bcc_mail)
	 ->addPart($vcal,'text/calendar');
	//Send the message
    $result = $mailer->send($message);

you can see from here i'm using swift mailer! any one know how to solve my problem?
i'm appreciate for any help!

PS: the email will be send out with an calendar invitation as attachment.
and my problem is i can't open the attachment! God!

Just try the following code and check wheather the calendar opens correctly or not.

header("Content-Type: text/Calendar");
header("Content-Disposition: inline; filename=calendar.ics");

$vcal = "BEGIN:VCALENDAR";
$vcal .= "VERSION:2.0";
$vcal .= "PRODID:-//CompanyName//ProductName//EN";
$vcal .= "METHOD:REQUEST";
$vcal .= "BEGIN:VEVENT";
$vcal .= "ATTENDEE;CN=\"Attendee1Name\";ROLE=REQ-PARTICIPANT;RSVP=FALSE:MAILTO:Att1Mail@mail.com";
$vcal .= "ATTENDEE;CN=\"Attendee2Name\";ROLE=REQ-PARTICIPANT;RSVP=FALSE:MAILTO:Att2Mail@mail.com";
$vcal .= "UID:".date('Ymd').'T'.date('His')."-".rand()."-besta.com.my";
$vcal .= "DTSTAMP:".date('Ymd').'T'.date('His');
$vcal .= "DTSTART:09/06/2011";
$vcal .= "DTEND:10/06/2011";
$vcal .= "LOCATION:Meeting room 2";
$vcal .= "SUMMARY:hahaha....meeting";
$vcal .= "BEGIN:VALARM";
$vcal .= "TRIGGER:-PT15M";
$vcal .= "ACTION:DISPLAY";
$vcal .= "DESCRIPTION:Reminder";
$vcal .= "END:VALARM";
$vcal .= "END:VEVENT";
$vcal .= "END:VCALENDAR";

echo $val;

exit;

thank for help
but where should i place your code?
you mean i don't send the email but echo it out to see the result 1st?

To Check wheather your calendar is working corect or not before it is attached to mail.

for the header i gain this error

Warning: Cannot modify header information - headers already sent by (output started at C:\xampp\htdocs\eform\accomodation\haha.php:2) in C:\xampp\htdocs\eform\accomodation\haha.php on line 5

what does it mean?

Your calendar is not opening. Try ur code with this script.

echo "BEGIN:VCALENDAR\n";
	echo "VERSION:2.0\n";
	echo "PRODID://Foobar Corporation//NONSGML Foobar//EN\n";
	echo "METHOD:PUBLISH\n"; // requied by Outlook
	echo "X-WR-CALNAME:PH2011\n";
	echo "X-WR-TIMEZONE:Asia/Singapore\n";
	echo "BEGIN:VEVENT\n";
	echo "UID:".date('Ymd').'T'.date('His')."-".rand()."-example.com\n"; // required by Outlok
	echo "DTSTAMP:".date('Ymd').'T'.date('His')."\n"; // required by Outlook
	echo "DTSTART:Your Date\n"; 
	echo "SUMMARY:Your Summary Here\n";
	echo "LOCATION: Your Location Here\n";
	echo "DESCRIPTION: Your Description Here\n";
	echo "END:VEVENT\n";
	echo "END:VCALENDAR\n";
